Names CH 34 SPHERICAL MIRRORS A CONVEX MIRROR: JURASSIC PARK (TOTAL 8 POINTS) 3. In the film "Jurassic Park", horrified passengers watch in a car's convex side-view mirror a dangerous dinosaur pursuing them. Printed on the mirror is the warning "OBJECTS IN THE MIRROR ARE CLOSER THAN THEY SEEM If the mirror's curvature radius is R 12m] and the dino is actually p9[m] from the mirror, by what factor does the dinosaur appear reduced in size? DRAWING AND EQUATIONS (3 POINTS) Make a sketch of the situation and determine the focal length of the mirror f CALCULATION (4 POINTS) Document your calculation: VIRTUAL OR REAL IMAGE (1 POINT)

Answer 1

SKETCH овест 6 m Back am THE FOCAL LENGTH OF THE MIRROR is om CALCULATE THE FACTOR BEES BY WHICH THE DINOSAUR APPEARS REDUCED IN SIZE. Matt - - f (S-F) S-f . Thus, M= I s-f = -(6m) am-(-6m) - 0.40 THUS, THE DINOSAUR IS REDUCED BY 60% ITS ORIGINAL S125. IT APPEARS ONLY 40% OF ITS ACTUAL SIZE.
